Оператор if всегда возвращает false при сравнении строк

I have used this code to try and confirm that the user input passwords are the same and there is no mismatch, before proceeding to the next activity. But the if statement always returns a false. It works fine for hardcoded text, but always returns a false for if. Am I missing something?

private void validate(EditText userPassword, EditText userConfirmPassword){
   String userPasswordtext = userPassword.getEditableText().toString();
  String userConfirmPasswordtext = userConfirmPassword.getEditableText().toString();

    if (userPasswordtext == userConfirmPasswordtext){
        Intent intent = new Intent(this, MainActivity.class);
        startActivity(intent);
    }else{
        Toast a=Toast.makeText(this, "Passwords do not match", Toast.LENGTH_SHORT);
        a.show();
    }
}
